I just purchased a Switch, which is connected to a Router, Desktop and Laptop. Internet works fine on both, however I was wondering how to facilitate data transfer b/w two PCs. Desktop has Ubuntu, Laptop has Mandriva. (A distro neutral approach would be appreciated since I also use Arch in the desktop) Previously I had tried networking with a crossover cable but failed . So I am n00b in networking, kindly help. Also guide in event of a Linux-Windows networking system. I also have Win7 on the desktop.
